[Comparison of clinical and histopathological diagnosis in oral surgery].

Only a successful cooperation of an oral surgeon and the pathologist can ensure a reliable diagnosis. The authors have analyzed operations performed during 1990 at outpatient clinic of the Department of Oral and Maxillofacial Surgery, University of Zagreb, School of Dentistry. Clinical appearance of the disease and clinical diagnosis sometimes enable us to recognize the real nature of the disease.

[Radiographic analysis of condyle position in patients with TMJ dysfunctions].

Decreased joint space is one of the basical radiographic signs of joint disease and correlation with crepitus the real clinical symptom of structural joint damage. The aim of this investigation is to find out if there is any correlation between the intrajoint condyle position and joint dysfunction symptomatology, by means of TMJ tomography evaluation. Among the patients with characteristic symptoms of TMJ dysfunction examined in our Departments, a group of hundred were tomographed (Polytom--Philips-Massiot).

[Retention of resection prostheses using endosteal implants].

Nine endosteal implants of Linkow, Sandhaus and Vitradent type and one transdental implant have been used in six patients for the retention of resection prostheses. The intention was to find out the efficiency of endosteal implants in prosthetic rehabilitation of patients with oncologic defects of jaws. Most implants were removed because of loosing and mucosa inflammation after the period of 46 to 139 days.

An alternative method of fixation of alveolar ridge mucosa during the vestibuloplasty procedure.

The authors present a new design of splintage for fixation of the alveolar ridge mucosa following various vestibuloplasty procedures. From 1981-1987 50 acrylic buccal splints and 76 palatal splints were used, fixed by AO screws, in vestibuloplasty procedures. By using screws a controlled pressure equally distributed over the mucosa was achieved.
